[cabesitas713]

ok so i have a ka-t t25 map enthalpy tuned 440cc injectors tune to a z32 maf it wont let me rev past 5k rpm lets say im driving normal and i reach a stop light or even just put it on neutral itll go all the way down too zero like almost shutting off for like 1 sec then goes back up too 1k sometimes it does turn off i checked the wiring on maf seems to be good i swapped to another z32 maf and same thing the weird thing is that i unpluged the maf and it was perfect wouldnt turn off or anything as soon as i try to connect it back my car would turn off any help would be appreciated im really annoyed by this :(

Your car should only rev to 2500 RPM with MAF unplugged (Limp mode). Do you have a wideband? What's your AFR's when it almost dies? Sounds like its runnin super rich, which most canned tunes are because its safe. Could be your MAF wiring, did you do it yourself? Did you shield the wires? Have you messed with the turbo inlet pipe at all?

check your IAC (Idle Air Control) because it may be clogged from running so rich
